When I 1st started with the E-trac all the 1 ferrous numbers turned out to be iron and after much digging of trash, I quit digging them. Recently I have dug some just to see what they were and they turned out to be clad pennies. Can someone explain to me what is going on with these numbers and why? They were not exceptionally deep targets.All were in the 3 to 6" range. Thanks! P.S. I live in Minnesota so I don't think mineralization is a factor.
